AI-suggested
Oracle strongly recommends applying the June 2026 Critical Security Patch Update as soon as possible to address this vulnerability. Although the advisory does not explicitly confirm a dedicated patch for CVE-2026-35309, the update includes 245 security patches covering multiple products including Oracle Coherence. Until patches are applied, risk may be reduced by blocking network protocols required for exploitation (e.g., HTTP access to Oracle Coherence) and by removing unnecessary privileges or access to vulnerable components from users who do not require them. These mitigations may affect application functionality and should be tested accordingly. Customers should monitor Oracle's advisory page for updates and patch availability confirmation.
